Description

Technical Field

[0001] The utility model relates to the technical field of automated grinding equipment, in particular to a grinding belt cleaning height adjustment unit. Background Art

[0002] Grinding refers to a processing method that uses abrasives to process the surface of an object to achieve the purpose of improving surface roughness, shape accuracy, dimensional accuracy, etc. In industrial production, grinding is often used to manufacture precision parts, improve surface quality, repair damaged surfaces, and other processes. Grinding usually uses the relative movement between the grinding tool and the workpiece to cut and grind the surface of the workpiece using abrasive particles to ultimately achieve the desired processing requirements. Grinding can be done in a variety of ways, such as manual grinding, mechanical grinding, chemical grinding, etc. The specific choice depends on the material, shape, and requirements of the object being processed.

[0003] In the existing grinding belt cleaning device, when the height of the grinding mechanism is readjusted, the grinding mechanisms on the upper and lower sides move synchronously. If the upper and lower sides of the workpiece require different grinding depths or height adjustments, the synchronous lifting may not be able to meet the needs. Since the workpieces have different thicknesses, if the grinding mechanisms on both sides of the workpiece cannot be controlled separately, they may not be suitable for workpieces of different thicknesses, limiting the flexibility of grinding. In view of the above problems, a grinding belt cleaning height adjustment unit is proposed to solve them. Utility Model Content

[0023] Preferably, two first movable rails 5 are fixedly connected to one side of the two supporting columns 1 close to the mounting plate 18, and the mounting plate 18 is slidably connected to the surface of the first movable rails 5 through a slider.
